Bankable Feasibility Study of Três Estradas Confirms Robust Project Economics

Open pit operation with a 16-year life of mine plus additional 20 years of aglime production from reclaimed tailings, totalling 36 years of operation
Phased production will focus on mining high-grade oxidized ore in initial years of operation – Phase 1 mining oxidized ore, Phase 2 mining fresh carbonatite ore and Phase 3 producing aglime only
Minimum tailings disposal with only 10% of tailings generated over the life of mine – reduced environmental footprint
Phosphate concentrate grading 30.1 to 32.7% P2O5, aglime concentrate grading 40% CaO with superior reactivity with a TNP of 84.7%
Optimizations to crushing circuit, milling circuit, flotation circuit, filtration all resulted in CAPEX and OPEX reductions
Market study confirms logistics cost advantage to displace phosphate imports and quality aglime by-product with no further processing required
